docs: fix npx command in README

[akurinnoy]

Summary

• Use --package (long form) instead of -p — the short form gets consumed by claude mcp add's flag parser, causing it to launch interactively instead of registering the MCP server
• Remove --transport stdio — it's the default, and --transport isn't recognized by current CLI versions

Before

claude mcp add --transport stdio che-mcp -- npx -p che-mcp-server che-mcp-bridge

After

claude mcp add che-mcp -- npx --package che-mcp-server che-mcp-bridge

Summary by CodeRabbit

• Documentation
  • Updated the Agent Quick Start instructions for local CLI setup.
  • Added clearer connection examples for both npx usage and a global install flow.
  • Improved formatting by separating the two setup paths for easier follow-through.
